Because the red and blue light give off a frequency that the plants are tuned to and that energizes the plant, just like a radio needs its own frequencies to play music, a plant needs its color freqencies for growth. 680nm and 430nm . Both of which are found in a Hydrogen light!

Why is red light different to blue light?

The red light is lower energy than the blue light.


Red and blue will absorb the same light?

Red and blue light will not absorb the same light. Red objects reflect red light and absorb other colors, while blue objects reflect blue light and absorb other colors.


What color do you get when you mix red and blue light?

You get magenta when you mix red and blue light. Magenta is a secondary color formed by combining red and blue light, which are on opposite ends of the visible light spectrum.


Which color of light is produced by mixing red light and blue light?

Mixing red light and blue light produces magenta light.


What color does blue and red make in light?

Blue and red light mix to create magenta light.


Does blue or red have a higher frequency?

Blue light has a higher frequency than red light. When we see different colors, we are actually perceiving different wavelengths of light - blue light has a shorter wavelength and higher frequency than red light.

When red light and blue light are both projected onto a white surface, they combine to create magenta light. Magenta light is a different color from red or blue, which is why we don't see red or blue individually in that situation.


How do the frequencies of blue light or red light compare?

Blue light has a higher frequency than red light. This means that blue light has shorter wavelengths and carries more energy compared to red light. Additionally, blue light is more likely to scatter in the atmosphere, leading to effects like blue skies during the day.


What is energy of blue light waves compared to red light?

Blue light waves have higher energy compared to red light waves because blue light has a shorter wavelength. This means that blue light photons have greater energy levels than red light photons.


What colour does blue look under a red light?

Under a red light, blue would appear dark or black because red light is absorbed by objects that are not red. Since blue is not a color in the red light spectrum, it cannot reflect or be seen under red light.
